Abstract
The conductance of frozen Wyoming bentonite suspensions was measured. The magnitude of the observed conductance was consistent with an expression derived from the assumption that the films of unfrozen water on the clay particle surfaces are continuous through the frozen soil matrix. For the range of water contents used, the conductance per gram of clay was found independent of water content in the frozen suspensions. There was a large difference in conductance between frozen and unfrozen soil; this difference was larger for Na than for Ca‐bentonite.
